GEORGE KIRCIIGPABER, OF ST. LAlVRENCE, DAKOTA TERRITORY.

FLOUR-CHEST.

SPECIFICATION forming part of Letters LPatent No. 398,736, datedFebruary 26, 1889.

Application filed April 16, 1888.

Be it known that I, GEORGE KIRCHGRABER, a citizen of the United States,residing at St. Lawrence, in the county of Hand and Territory of Dakota,have invented certain new and useful Improvements in Flour-Chests; and Ido declare the following to be a full, clear, and exact description ofthe invention, such as i will enable others skilled in the art to whichit appertains to make and use the same,referenee 1 being had to theaccompanying drawings, 1 and to the letters and figures of referencemarked thereon, which form a partof this specification.

The special object of the invention is to make the sieve and itssupports so that it may be put in and taken out without interfering iwith the flexible rubber which extends from the hopper-hole nearly orquite to the bottom l of the sieve, the raised pocket at one end prc- Qventing the sieve from being drawn back and E out of the chest.

Figure 1 of the drawings is a vertical section; 2, a horizontal sectionon line m, Fig. l; Fig. '3, a vertical section showing the sieve in aposition to be removed; Fig. 4', an 1 end view, partly in section; Fig.5, a detail perspective view of the sieve.

In the drawings, A represents the chest, and B the hopper, with a hole,I), surrounded by the rubber I), which is flexible, and projects nearlyto the bottom of the sieve, so as to guide the flour down to the sicv?without spreading it laterally thereon.

I is the door through which the sieve is partly drawn back before it istaken out. The sieve is made of a woven-wire fabric, I), 1 on the bottomand sides, said fabric being brought up over the ends of the sidepieces, G C, and extendedinwardly forsomedistance to prevent the escapeover the ends of the impurities lodging in the pockets 0 c. On thebottom of the rabbeted sides C C are i made fast the cross-pieces F F,which project beyond them and slide on the cleats G G, made fast to thesides of the chest A, at the same height and directly opposite eachother. Two cleats are on each side with an interme diate open spacethrough which the ends of l the cross-pieces F may pass.

E is the rod by which the sieve is moved horizontally back and forth inorder to make the flour pass therethrough.

The chest is used as follows: The flour, hav- To all whom it mayCOILOCT'IZ. I i s Serial No. 270,769. (No model.)

ing been emptied from the bag or other receptacle into the chest, findsits way by its own gravity through hopper and rubber spout or guide tothe sieve, upon which the lower end of the column rests. hen the cook orbaker wishes, the sieve is reciprocated until as much as is needed hasbeen deprived of its impurities, which are caught in the pockets. Thedrawer is then removed to pour the flourinto some other receptacle, orthe flour is taken out of the drawer without the removal of the latterby a scoop. After the flour has been all used and the chest is empty,the drawer is first removed and then the sieve, so that the impuritiesmay be emptied from the pockets.

The sieve cannot be inserted in place or removed therefrom by ahorizontal movement on account of the projecting rubber Z) and theelevation of the ends 0 0' above the bottom of sieve; hence the sieve isfirst drawn to the position shown in Fig. 3 of the drawings, and thencarried down to the position shown in dotted lines, when it is drawn outentirely. This operation is reversed in order to put the sieve intoplace, so that the cross pieces F shall rest on the cleats G. In bothoperations the drawer II is first taken out.

I am aware that the chest with top-hinged door and the hopper withprojecting rubber about the hole Z1 thereof are old; also, that sieveshave been used with pockets; but

\Vhat I claim as new, and desire to protect by Letters Patent, is-

1. A flour-chest s'eve consisting of the side pieces, C C, covered atthe ends by woven wire, and the cross-pieces F I, supporting a bottom ofwoven wire, pockets co being thus formed to extend above and below thesievebottom.

2. The combination of a flour-chest having side cleats, G G, and a sievehaving crosspieces F F, extended to rest on them, the cleats andcross-pieces on each side being separated by an intervening space, asshown, whereby the sieve maybe put in or taken out, as described.

In testimony whereof I a div my signature in presence of two witnesses.
